Kev Taw Qhia rau Sintered Copper Clutch Friction Disc
I. Lub ntsiab txhais thiab cov ntsiab lus tseem ceeb
A Sintered Copper Clutch Friction Disc yog qhov ua tau zoo -kev sib txhuam cov khoom tsim los ntawm cov hmoov hlau metallurgy. Nws siv electrolytic tooj liab hmoov ua lub ntsiab matrix (feem ntau accounting rau ntau tshaj 60%), thiab yog tsim los ntawm cov txheej txheem xws li hmoov sib tov, txias nias, thiab siab - kub sintering nrog rau qhov sib ntxiv ntawm ntau yam alloying ntsiab thiab ua hauj lwm fillers.
Nws txais ib qho qauv sib xyaw ua ke:steel thaub qab + hloov txheej + sintered tooj liab txhuam txheej. Lub nraub qaum steel muab kev txhawb nqa nruj, thaum txheej kev sib txhuam ua haujlwm torque kis tau tus mob thiab kev sib txhuam kabmob.
II. Material Formula thiab Manufacturing txheej txheem
1. Cov khoom siv tseem ceeb (Cov qauv zoo tib yam)
| Hom Lub Npe | Cov khoom xyaw tseem ceeb | Cov ntsiab lus ntau | Core Function |
|---|---|---|---|
| Matrix Khoom | Electrolytic Copper Hmoov | 60-80% | Muab siab thermal conductivity, zoo heev hluav taws xob conductivity thiab toughness |
| Alloy Strengthening Phase | Tin, Zinc, Nickel, Molybdenum | 5-15% | Txhim kho lub zog, hardness thiab hnav tsis kam |
| Friction Modifier | Graphite, Molybdenum Disulfide | 5-10% | Stabilize kev sib txhuam coefficient, txo hnav thiab suab nrov |
| Txhim kho Phase | SiC, Al₂O₃, Ceramic Particles | 3-8% | Txhim kho siab -kub stability thiab cuam tshuam tsis kam |
| Cov khoom xyaw ntxiv | Hlau hmoov, sulfides | 2-5% | Optimize ceev thiab kev sib txhuam kev ua haujlwm |
Niaj hnub nimno siab- khoom kawg feem ntau txais yuavasbestos-dawb thiab lead-dawb eco- cov qauv zoo, ua raws li cov qauv thoob ntiaj teb ib puag ncig xws li RoHS.
2. Cov txheej txheem tsim khoom tseem ceeb
Batching thiab hmoov sib tov: Sib npaug txhua qhov sib xyaw ua ke thiab sib tov sib npaug hauv qhov sib xyaw ua ke rau 4 mus rau 8 teev.
Cold Press forming: Compress cov hmoov sib tov rau hauv preforms nyob rau hauv lub siab ntawm 100-300 MPa.
High -Tsub Sintering: Sinter nyob rau hauv lub tshuab nqus tsev los yog tiv thaiv huab cua ntawm 900-980℃(tshwj xeeb kub rau tooj liab puag) kom paub metallurgical bonding ntawm hmoov hais.
Shaping thiab Machining: Ua precision txiav thiab sib tsoo kom ntseeg tau qhov tseeb qhov tseeb (kev ua siab ntev ± 0.02mm) thiab nto flatness.
Kev kho saum npoo: Kev xaiv los tiv thaiv- kev kho corrosion xws li galvanizing thiab passivation kom ntev kev pab cuam lub neej.
III. Core Performance Parameters (vs. Hlau -Raws li Sintered Friction Disc)
| Performance Index | Sintered tooj liab txhuam Disc | Hlau -Raws li Sintered Friction Disc | Lus hais |
|---|---|---|---|
| Kev sib txhuam coefficient (μ) | Qhuav: 0.25-0.40; Dej: 0.08-0.35 | Qhuav: 0.35-0.50; Dej: 0.10-0.40 | Lub hauv paus tooj liab nta ntau dua stability nrog me me fluctuation |
| Ua haujlwm kub siab tshaj plaws | Tam sim no: 600 degree; Nruam: 400 degree | Tam sim no: 800-1200 degree; Nruam: 600 degree | Hlau puag muaj zoo thermal stability |
| Thermal conductivity | 80-120 W/m·K | 40-60 W/m·K | Thermal conductivity ntawm tooj liab puag yog tshaj ob zaug ntawm hlau puag |
| Counterpart Hnav | Tsawg (qis adhesion thiab seizing nyiam) | Siab zoo (yooj yim affinity nrog steel / cam khwb cia hlau) | Copper puag tiv thaiv flywheel thiab siab phaj |
| Qhov ntom | 6.0-6.8g / cm³ | 6.5-7.2 g / cm³ | Lub hauv paus tooj liab yog me ntsis sib zog nrog lub sijhawm qis ntawm inertia |
| Torque Capacity | Nruab nrab (200-800 Nm) | Siab (400-1500+ Nm) | Hlau puag haum rau siab -horsepower applications |
| Hnav Resistance | Zoo heev nyob rau hauv ntub tej yam kev mob, zoo nyob rau hauv qhuav tej yam kev mob | Zoo heev nyob rau hauv qhuav tej yam kev mob, nruab nrab nyob rau hauv ntub tej yam kev mob | Lub hauv paus tooj liab siv tau rau cov clutches ntub dej |
